H9 33% Pawnee Tug Conversion

If I had a dine for everyone of those doors people have lost........... well, Id probably have a couple buck, but regardless I've heard that happens a lot. anything you can do to make it better is good, tape it for sure.

Sounds good. Will just go with duplicating the stock mechanism and tape.

The only issue I've had with the stock latch is the hole in the fuse enlarging from vibration. Stock latch plus taping seems to work fine. It's usually the wood at the bottom that fails. But looks like you've reinforced that nicely.

My tired old Pawnee (I'm the 3rd owner) lost the right door the other day. Almost finished fabricating a new slightly more reinforced replacement but was wondering if I should duplicate the stock locking mechanism or is there a better solution? I plan on taping both doors in the future. At least the leading edges.

I have just acquired a Pawnee, the upper L/G support bolts bent and I have replaced them with 5mm bolts and added 3/16 ply reinforcement to the box. The tires crumbled and I have added new wheels. My problem is "slack" in the support tubes where the springs fit. I can lift up the L/G about half an inch before the spring come into action. Does anyone know the size of replacement springs from McMasters? I can make a video if this is not clear

That's in this other Pawnee thread..

Here's a link to the thread on how I installed releases on both of my Pawnees.

You need something like this. http://www.icare-icarus.com/Remote-t...ne_p_1230.html

Need to add a bulkhead and use a decent metal gear servo.

Hello all, new to this forum. I am about to purchase a Hngr 9 Pawnee, but it does not have a tow mechanism. Where would I purchase one?

[Sinkhappens86]

Pretty sure I drilled mine out to accept 1/4". I've gone through a lot of axles...

[BryanB]

Has anyone had to replace their wheel axles? If so did you buy 6mm shaft or drill out the gear to accept 1/4"?

Thanks,BB

[BryanB]

Those Sullivan wheels look good. Thanks.

But if you really want the Dubro, I have two 7" for the price of one.

Definitely the Sullivan Skylite. With the round profile, puts much less side load on the gear. The Dubro are flat profile and put much more side load on the gear when turning.

This is what I've been using on mine. Other guys are happy with the Sullivan Sky Lite Wheels.
